Zunhua Office Chair Rotation Tester
"Zunhua Office Chair Rotation Tester" is not a widely recognized specific brand or model name, but an office chair rotation tester is a professional device used to evaluate the durability and service life of rotating office chairs. The following provides an introduction from aspects such as device principle, standard basis, core parameters, common models, and manufacturers:
Device Principle: An office chair rotation tester fixes the office chair's footrest on a test disc, applies a specific load to the seat surface, and sets the number of cycles and time to simulate the rotating motion of the office chair during long-term use, thereby evaluating its durability. For example, during the test, the device will make the office chair rotate continuously according to preset parameters, record its state after reaching the specified number of cycles, and determine whether there is any damage or performance degradation.
Standard Basis: Its design and testing are mainly based on relevant standards such as the American BIFMA and QB/T 2922 - 2007. These standards provide detailed regulations on various indicators and testing methods for office chair rotation tests, ensuring the accuracy and reliability of the test results, so that office chairs produced by different manufacturers can be evaluated for quality under unified standards.
Core Parameters: These include disc diameter, test speed, seat height, and applied load. The parameters vary among different models of the device. For example, the HD - 104 model has a seat height of 350 - 600 mm, a load capacity of 225 Lb, a disc diameter of ฮฆ700 mm, and a test speed of 6 rotations per minute; the HD - F731 model is equipped with a 2kN sensor, has a test force range of 0.2 - 1.8kN, and a test speed of 10 ยฑ 5 r/min.
Common Models and Manufacturers: There are various models of office chair rotation life testers on the market. For example, the LT - JJ06 is produced by Dongguan Lituo Testing Instruments Co., Ltd.; the KJ - 5101 is manufactured by Dongguan Kejian Testing Instruments Co., Ltd.; and the XQ - 897 is produced by Dongguan Xingqiao Instrument Equipment Co., Ltd. These different models of devices have their own characteristics in terms of functions and performance, meeting the testing needs of different users.
